Dow AFFINITY™ SQ 1503 UE Impact Modifier

Affinity™ SQ 1503UE is a polyolefin plastomer made with Dow’s INSITE™ technology, optimized for rotational moulding. It combines easy demoulding with the flexibility and elastic recovery of polar copolymers, featuring excellent heat and UV stability, wide processing latitude, and long-lasting performance.

Features Of Dow AFFINITY™ SQ 1503 UE Impact Modifier

  1. Optimized for rotational moulding with easy demoulding, reducing production cycle times and improving efficiency.

  2. Delivers flexibility and elastic recovery comparable to EBA, EVA, and plasticized PVC, without the need for polar copolymer feedstocks.

  3. Enhanced heat and UV stability for extended service life, even in outdoor and demanding environments.

  4. Wide processing latitude and excellent color retention, supporting consistent, high-quality finished parts.

  5. Supplied as a free-flowing powder (500 μm particle size) for uniform feeding and processing in rotational moulding equipment.

Typical Applications Of Dow AFFINITY™ SQ 1503 UE Impact Modifier

  1. Marine and offshore applications such as buoys and fenders, leveraging its durability and UV resistance.

  2. Highway safety products including road furniture and crash barriers, requiring impact resistance and long-term performance.

  3. Rotationally moulded tanks and containers for chemical storage, benefiting from its chemical resistance and ESCR performance.

  4. Outdoor recreational equipment like kayaks and playground components, where flexibility and weatherability are key.

  5. Protective covers and housings for industrial equipment, relying on its toughness and dimensional stability.
